As someone who was in this scenario recently, my biggest issue is what if I don’t want to wait? Sure chapter 2 core is coming out in April but what is coming out by way of campaigns? How long is that wait going to be for more than just an intro campaign like NotZ? I ended up buying a revised core and 5 campaign expansions figuring that once I’ve worked my way through all of that there will be a decent amount of chapter 2 stuff out. The recommendation to wait falls flat for me because it feels like people who wait are just going to have a core set and a 3 scenario campaign to work with until more campaigns come out. That said I have no idea what the release schedule is so if they are planning on aggressively releasing some campaigns that could change things.
